Extended UPVC Bulkhead Union Coupling (20-75mm) | Space-Saving Tank Connector for 0-25mm Glass | Aquarium & Sump

Extended UPVC Bulkhead Union Coupling (Space-Saving)

Solve your thick-glass plumbing challenges with the Extended UPVC Bulkhead Union Coupling from Atradesen.com. Uniquely designed with an extended body, this fitting securely clamps onto tank walls up to 25mm thick. Its innovative "same-hole" space-saving design means the drill hole required is significantly smaller than traditional bulkheads, preserving the structural integrity of your glass or acrylic tanks.

🌟 Advanced Plumbing Features

• Extended Clamping Range: Perfect for extra-thick aquariums, custom sumps, and commercial vats, easily accommodating wall thicknesses from 0mm to 25mm.
• Space-Saving "Small Hole" Design: The threaded central shaft is highly compact, allowing you to drill a hole equal to (or even slightly smaller than) the pipe's outer diameter!
• Dual Silicone Seals: Equipped with premium silicone gaskets on both sides for maximum elasticity, providing an impenetrable, long-lasting watertight barrier.
